摘要
Partial heat treatment for the tungstena body of a munition round to adjust tensile strength and ductility of the tip of the round has the tip dipped in high temp. molten salts. The material is embrittled or the ductility lowered in a localised area of the tip at a emp. 80 deg. C. above the last heat treatment temp. of the whole round. USE/ADVANTAGE - tungstenm penetrator mfr. Gives repeatable and controllable partial heat treatment results in batch prodn. mfr.
